s ita KILN HEATNG CHAMBERS AND COOLING CHAMBERS..

To all whom it may concern;

Beit known that I, Vieron' Gf'nnrnma citizen ofthe' Helvetic Confederation, and resident of Luzern, Reckenbhlstr. 2, Switzerland, have invented a certain new and useful Improved Kiln with Heating Chambers and Cooling Chambers, oit which the following is a specification.l

f This invention `relates to a kiln having a heating space or chamber and coolingspace or chamber or a plurality of suchones. The gist of' the invention resides in the teature that the cooling-chamber is connected with a 'yielding member, the object ot' which is to prevent that the expansion or extension of the heating-chamber due to the heating is transmitted to the cooling-chamber in a manner likely to do damage to this chamber.

Itis, already known with tubes, itis true, to compensate elongations due to heat by means of compensating-pipes or the like inserted into the tubing at suitable places, but

such pipes are applicable only in connection with tubes orpipes or circular section. They are provided with circular ringsl at their flanges and are merely adapted to compensate a uniform extension taking place in the longitudinal axis pipes.

ln contradistinction to this known contrivance, the compensating-meansV employed in connection with the improved kiln is apt` tor use in connection with any desired proile, especially such as that of a chamber of the kind in question, and it allows ot compensating extensions in the -axial direction, also if they are different at different parts of the circumference of the chamber. They may, for instance, be greater in the upper part of the chamber than in the lower part. But also movements of different` magnitude in transverse directions are effectively compensated by the novel member in question.l as will appear trom the following.

In order to make my invention more clear, I refer to the accompanying drawing, in which similar letters denote similar parts throughout the several views, and in which,

ot the respective tubes or Figure 1 is a longitudinal section through a tively, which contains the heatingchamber 2. 4 is the cooling-chamber, and 3 is a slide valve casing having a slide valve 22 ar` ranged between the'chambersQv and 4. By this slide-valve 22 the interiors ottheicham` bers 2 and 4 are divided'froinmone another. The slide-valve is combined'with ayielding lmember 5 which in its simplest form'of cons i .into the heating one. The plates 6 have cenv y tral openings `corresponding in width `to 'the Y,

clear width of the chamber 4,y aswell aste Specication of Letters Patent. y FQEMQ@ Aug, 15, 1922i@ Applicationiaea March' 16, 1921. serieu No. 452,827. y' 7 i i A that of the slide-valve` 3, and they are coni nected with these parts and 4) alsoga-stight by screws 9, as shown in'Figuresl and 3. i'

ln the enlargedillustrat'i'on Figure 3 the construction is slightly different fromv Figure 1, because the sheet-metal plates 10 which form the compensatingemember are completely fiat and connected at their rims by` ledges 11 (see also Figure 2) and bolts 72 InV all 'other :respects the construction is exactly the same as that already described.

rllhe yielding 4'member or compensating member 6 6, or 10-10 respectively, lneed not be arranged between the'slidevalve cas- 1 ing and the cooling-chamber, but 4may be arranged also between the slide-valve and the heating-chamber, .or it maybe arranged at the rear end of the cooling-chamber; and where instead of only one cooling-chamber two or more are made use of, there also more than one compensatingemember maybe provided.

The'coolingfchamber has atand below-its bottom ribs 12 which are adapted to roll` upon rollers 13 supported by the base or.

socle 14. The chamber 4 with'its contents is thus carried by said. base or socle 14. The contents consists, in the example shown, of a truck 15 loaded with certain articles of roo manufacture which are first to be annealed and then to be cooled.

16 is a horizontal plate whichA extends through the compensatingmember and is affixed, in the example shown, by screws 17 to the slide-valve casing 3. lit the opposite rim of saidplate 16 are holes receiving the headset pins 19. rhe diameter of the pinheads is somevvnat smaller than that of the plate-holes, there being lett some dead play 16 (Fig. which determines the extent of the relative motion between the parts 3 and l.

1t appears trom What has been described and slioivn that the longitudinal movements ot the heating-chamber and the slidevalve casing is compensated by the compensatinganember, in that the one `plate approaches the other as much as allowed by the. dead play 16; Then the cooling-chamber is displaced and moved upon the rollers 13.

These may be dispensed with, it also thel plate 16 is dispensed with, when the Whole extent ot the elongation or the heatingchamber is taken up by the member 6 6 or 10-10.

The'eX/tent ot the elongation may be dii"- ferent in different parts of the heating;- chamber; it may be greater at the top 2O than at the bot-tom 21. Also movement or expansion in transverse direction may be compensated and rendered ineffective by the member in question. liilith'out this latter, any one, or several, ot the llanges located at or between the chambers are exposed to the risk oit being` broken off.

lf the compensating-member is to compensate only such small extensions as may occur after the heating operation has been finished, the plate 16 may be arranged in the manner described Vand shown when the dead-play 18 will determine the extent oil motion not to be transmitted to the coolingchamber, Whereas any surplus makes this chamber move upon the rollers 13. A movearise on the chamber or parts concerned cooling down when the direction of motion- Will be, of course, the reverse -otvvliat ithas previously been.

rlhe arrangement of the plate 16 oi'ers, besides,the further advantagethat the transmission oi the forces arising from the heating-chamber bottom to the coolinglchamber bottom is effected Without any comparatively strong bending-stress, in contradistinction to connections by iange-sorews which entail considerable bending stresses.

Having now described my invention7 What l desire to secure by a Patent ofthe United States is:

1. lrilmcomprising, in combination, a furnace, a heating-chamber, a coolingchamber, and a compensatingfmember arranged between said chambers; said member consisting ot two sheet-metal plates ari ranged in an appropriate distance one from the other, antigas-tight connectionsbetween said plates, as Well-as between them andthe structure-components with which they. are connected.

2. t kiln, comprising, in combination, a furnace, a heating-chamber, a cooling-chamber, a compensating-member between said chambers, a plate firmlyconnectedwvithone side ot said member, a hole inthevopposite end of said pla-te, a stud extending through said holD into apart connected with the ther side of the said'member,.the relative diameter of the said hole and said stud besuch that some dead play isleft, for the purpose set forth.-
